增材制造技術（也稱3D打印技術）在發展新型TiAl合金領域有巨大潛力。電子束熔煉技術制備TiAl合金逐漸引起關注，本文對相關工藝探索的研究進行了綜述。通過調節EBM過程中的各工藝參數，例如片層厚度、熔煉溫度、掃描速率、線能量和構建路徑等參數，可獲得致密并且無大量Al損失的均勻樣品。經過熱等靜壓處理和熱處理，可得到細小均勻的組織。通過控制熱處理溫度，可獲得等軸晶組織、雙態組織（片層比率不同）或全片層組織。總結了EBM技術的優點和存在問題，并對其發展前景進行了展望。

Additive manufacturing (3D printing) holds strong potential for the production of a new class of TiAl alloys. In the present paper, recent research progress on the processing TiAl alloys by electron beam melting was reviewed. The EBM parameters such as layer thickness, melting temperature, scanning speed, line energy, or building strategy were set up to minimize porosity and achieve a homogeneous specimen with less Al loss. The very fine microstructure resulting after EBM can be then set up by HIP and heat treatment(HT). According to the HT temperature in particular, an equiaxed microstructure, a duplex microstructure with different lamellar radio and a fully lamellar microstructure were obtained. Summary remarks were presented on the advantageous aspects of EBM and the prospect of this technique also.
